Copyright © 2024 Avtech Electrosystems Ltd, All Rights Reserved. __________________________________________________________________ 6 INTRODUCTION The AVMR-2D-B is a high performance, GPIB and RS232-equipped instrument capable of generating up to 20V into 50Ω loads at repetition rates up to 10 MHz . The output pulse width is variable from 0.3 to 200 ns. The rise time (20%-80%) is 200 ps or less. The fall time is 200 ps or less for pulse widths greater than 6 ns (app roximately). Below that, the rise time increases to 250 ps or less. Instruments with the "-P" model suffix can generate up to +20V, whereas instruments with the "-N" model suffix can generate up to -20V. Instruments with th e "-PN" suffix can generate both polarities. Two pulse width ranges are used internally, with range switching occurr ing at 6 ns, approximately. The instrument automatically selects the appropriate ran ge, but there may be a pause in triggering as the internally relays switch. Similarly , two amplitude ranges are used, with range switching occurring at 3.4V, approximately. An internal relay-switched 15 dB attenuator is used to provide the lower amplitudes . The AVMR-2D-B is a highly flexible instrument. Aside from the internal trigger source, it can also be triggered or gated by external TTL-level signals. A front-p anel pushbutton or a computer command can also be used to trigger the instrument. The AVMR-2D-B features front panel keyboard and adjust knob control of the output pulse parameters along with a four line by 40-character backlit LCD dis play of the output amplitude, pulse width, pulse repetition frequency, and delay. T he instrument includes memory to store up to four complete instrument setups. The ope rator may use the front panel or the computer interface to store a complete “snapshot ” of all key instrument settings, and recall this setup at a later time. This instrument is intended for use in research, development, test and calibration laboratories by qualified personnel. __________________________________________________________________ 7 AVAILABLE OPTIONS The AVMR-2D-B is available with several options: -OT Option: this option adds an internally-generated 0 to ±5V DC offset to the main output. -EO Option: the DC offset can be controlled by an externally generated 0 to +10V analog control voltage. -EA Option: the amplitude can be controlled by an externally generated 0 to +10V analog control voltage. -M Option: a monitor output is provided. -R5 Option: A rack mounting kit is available. The -R5 rack mount kit ma y be installed after first removing the one Phillips screw on the side panel adjacent to the front handle. -VXI Option: Adds a rear-panel Ethernet connector, allowing the instrum ent to be remotely controlled using the VXI-11.3, ssh (secure shell), telnet, and http (web) protocols. In particular, the VXI-11.3 features allows software like La bView to control an instrument using standard VISA communications drivers and network cabli ng, instead of using old-style GPIB cabling. (This eliminates the need for a GPIB c ontroller card and its proprietary drivers.) __________________________________________________________________ 8 SPECIFICATIONS Model1: AVMR-2D-B Amplitude2: (50 Ohm load) < 4 to 20 Volts Pulse width (FWHM): 0.5 to 200 ns PRF: 0 to 10 MHz Duty cycle: 10% maximum Rise time (20%-80%): ≤ 200 ps Fall time (80%-20%): ≤ 200 ps for pulse widths > 6 ns, ≤ 250 ps for pulse widths < 6 ns Polarity3: Positive or negative or both (specify) Required load impedance: 50 Ohms7 Propagation delay: < 150 ns.

P OWER Switch . This is the main power switch. When turning the instrum ent on, there is normally a delay of 10 seconds before anything is shown on the main display, as the internal operating system boots up. If the main menu does not appear after 30 seconds, turn off the instrum ent and leave it off for at least 60 seconds before applying power again. 2. O VERLOAD Indicator . When the instrument is powered, this indicator is normally green, indicating normal operation. If this indicator is yellow, an int ernal automatic overload protection circuit has been tripped. If the unit is overloaded (by operating at an exceedingly high duty cycle or by operating into a very low imped ance), the protective circuit will disable the output of the instrument and turn t he indicator light yellow. The light will stay yellow (i.e. output disabled) for about 5 s econds after which the instrument will attempt to re-enable the output (i.e. light g reen) for about 1 second. If the overload condition persists, the output will be disabl ed again (i.e. light yellow) for another 5 seconds. If the overload condition has been removed, the instrument will resume normal operation. This overload indicator may flash yellow briefly at start-up. This is n ot a cause for concern. Note that the output stage will safely withstand a short-circuited load condition. 3. O UT CONNECTOR . This SMA connector provides the main output signal, in to load impedances of 50 Ohms. 4. S YNC OUT . This connector supplies a SYNC output that can be used to t rigger other equipment, particularly oscilloscopes. This signal leads (or lags ) the main output by a duration set by the "DELAY" controls and has an approximate amplitude of +3 Volts to RL > 50Ω with a pulse width of approximately 1 00 ns. 5. L IQUID CRYSTAL DISPLAY (LCD) . This LCD is used in conjunction with th e keypad to change the instrument settings. Normally, the main menu is di splayed, __________________________________________________________________ 19 which lists the key adjustable parameters and their current values. The “Programming Manual for -B Instruments” describes the menus and submenu s in detail. 6. K EYPAD . Control Name Function MOVE This moves the arrow pointer on the display. CHANGE This is used to enter the submenu, or to select the operating mode, pointed to by the arrow pointer. ×10 If one of the adjustable numeric parameters is displayed, this increases the setting by a factor of ten. ÷10 If one of the adjustable numeric parameters is displayed, this decreases the setting by a factor of ten. +/- If one of the adjustable numeric parameters is displayed, and this parameter can be both positive or negative, this changes the sign of the parameter. EXTRA FINE This changes the step size of the ADJUST knob. In the extra- fine mode, the step size is twenty times finer than in the normal mode. This button switches between the two step sizes. ADJUST This large knob adjusts the value of any displayed numeric adjustable values, such as frequency, pulse width, etc. The adjust step size is set by the "EXTRA FINE" button. When the main menu is displayed, this knob can be used to move the arrow pointer. __________________________________________________________________ 20 REAR PANEL CONTROLS 4 8 11 1 3 9 DC OFFSET GATE A OUT OT AMP INT EXT ON OFF RS-232 TRIG MON GPIB 5 6 7 10 2 Note: some connectors may be in different positions than shown above, d epending on the exact combination of options ordered. 1. A C POWER INPUT . An IEC-320 C14 three-pronged recessed male socket is provided on the back panel for AC power connection to the instrument. O ne end of the detachable power cord that is supplied with the instrument plugs in to this socket. 2. A C FUSE DRAWER . The two fuses that protect the AC input are located i n this drawer. Please see the “FUSES” section of this manual for more informat ion. 3. D C FUSES . These two fuses protect the internal DC power supplies. Ple ase see the “FUSES” sections of this manual for more information. 4. G ATE . This TTL-level (0 and +5V) logic input can be used to gate the triggering of the instrument. This input can be either active high or active low, dep ending on the front panel settings or programming commands. (The instrument triggers normally when this input is unconnected). When set to active high mode, this inp ut is pulled- down to ground by a 1 kΩ resistor. When set to active low mode, this in put is pulled- up to +5V by a 1 kΩ resistor. 5. T RIG . This TTL-level (0 and +5V) logic input can be used to trigger t he instrument, if the instrument is set to triggering externally. The instrument triggers on the rising edge of this input. The input impedance of this input is 1 kΩ. (Dependi ng on the length of cable attached to this input, and the source driving it, it m ay be desirable to add a coaxial 50 Ohm terminator to this input to provide a proper trans mission line termination. The Pasternack (www.pasternack.com) PE6008-50 BNC feed-thr u 50 __________________________________________________________________ 21 Ohm terminator is suggested for this purpose.) 6. G PIB Connector . A standard GPIB cable can be attached to this connect or to allow the instrument to be computer-controlled. See the “Programming Manual f or -B Instruments” for more details on GPIB control. 7. R S-232 Connector. A standard serial cable with a 25-pin male connecto r can be attached to this connector to allow the instrument to be computer-contr olled. A user name (“admin”) and a password (“default”, as shipped from the factory) are required when logging into a serial terminal session. The internal controller at tempts to auto- sense the parity setting. It may be necessary to send a few return char acters before attempting a login in order to provide enough data to allow this auto-s ensing to work. (A standard Linux “agetty” process is used to implement serial control internally.) See the “Programming Manual for -B Instruments” for more details on RS-232 control. 8. N etwork Connector . (Optional feature. Present on -VXI units only.) Th is Ethernet connector allows the instrument to be remotely controlled using the VXI -11.3, ssh (secure shell), telnet, and http (web) protocols. See the “Programming Manual for -B Instruments” for more details. 9. A MP Connector . (Optional feature. Present on "-EA" units only.) The o utput amplitude can be set to track the voltage on this input. Zero Volts in correspond s to zero amplitude output, and +10V in corresponds to maximum amplitude out. Thi s mode is activated by selecting "Ext Control" on the front-panel amplitude menu, or with the "source:voltage external" command. 10. M Connectors . (Optional feature. Present on "-M" units only.) The mon itor output provides an attenuated replica (÷ 11) of the voltage on the main output . The monitor output is designed to operate into a 50 Ohm load. The monitor output do es not include the effect of the internal 15 dB attenuator that is used to provide mai n output amplitudes of 3.4V or less. 11. Depending on the selected options, these offset-related controls ma y also be present: OS Connector. (Optional feature. Present on units with the -OS option o nly). This connector allows an externally generated DC offset to be added to the o utput. The desired DC offset is applied to this connector, which is connected to t he output centre conductor through a high-quality RF inductor. Do not exceed ±50V, 250 mA. DC OFFSET OT ON/OFF Switch. (Optional feature. Present on units with th e -OT and -EO options only). If this switch is set to “ON”, the instrument genera tes a DC offset internally. The magnitude of this offset is controlled by the front pan el settings (if the DC OFFSET INT/EXT switch is in the INT position) or by the control volt age applied to the “A” connector (if the DC OFFSET INT/EXT switch is in the EXT positi on.) If this switch is set to “OFF”, a user-generated DC offset may be connected to the “DC OFFSET OUT” BNC connector. Do not exceed ±50V, 250 mA. __________________________________________________________________ 22 DC OFFSET OUT Connector. (Optional feature. Present on units with the - OT and - EO options only). This connector allows an externally generated DC offs et to be added to the output. The desired DC offset is applied to this connector, whic h is connected to the output centre conductor through a high-quality RF inductor. Do not exceed ±50V, 250 mA. This offset is only applied if the DC OFFSET INT/EXT switch is in the EXT position. DC OFFSET A Connector. (Optional feature. Present on units with the -EO option only). If the DC OFFSET INT/EXT switch is in the EXT position, a 0 to + 10V control voltage applied to this input will vary the output DC offset over the r ange of -5V to +5V, approximately. DC OFFSET INT/EXT Switch. (Optional feature. Present on units with the -EO option only). Determines whether the output DC offset is controlled by the fro nt panel settings (INT), or by a 0 to +10V control voltage applied to the “A” connector ( EXT). __________________________________________________________________ 23 GENERAL INFORMATION BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an ext ernal TTL trigger signal. In either case, two output channels respond to the trigger: OUT and SYNC.  OUT. This is the main output.  SYNC. The SYNC pulse is a fixed-width TTL-level reference pulse used to trigger oscilloscopes or other measurement systems. When the delay is s et to a positive value the SYNC pulse precedes the OUT pulse. When the delay is set to a negative value the SYNC pulse follows the OUT pulse. These pulses are illustrated below, assuming internal triggering and a positive delay: 100 ns, FIXED SYNC OUT (generated by the 3V, FIXED internal oscillator) DELAY > 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Figure A If the delay is negative, the order of the SYNC and OUT pulses is rever sed: 100 ns, FIXED SYNC OUT (generated by the 3V, FIXED internal oscillator) DELAY < 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Figure B __________________________________________________________________ 24 The next figure illustrates the relationship between the signal when an external TTL- level trigger is used: > 50 ns TRIG TTL LEVELS (external input) (0V and 3V-5V) PROPAGATION DELAY (FIXED) 100 ns, FIXED SYNC OUT 3V, FIXED DELAY > 0 PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT Figure C As before, if the delay is negative, the order of the SYNC and OUT puls es is reversed. In general, the delay, pulse width, and frequency (when in the internal mode), of the OUT pulse can be varied with front panel controls or via the GPIB or RS -232 computer interfaces. TRIGGER MODES This instrument has four trigger modes:  Internal Trigger: the instrument controls the trigger frequency, and ge nerates the clock internally.  External Trigger: the instrument is triggered by an external TTL-level clock on the back-panel TRIG connector.  Manual Trigger: the instrument is triggered by the front-panel “SINGLE PULSE” pushbutton.  Hold Trigger: the instrument is set to not trigger at all. These modes can be selected using the front panel trigger menu, or by u sing the appropriate programming commands. (See the “Programming Manual for -B Instruments” for more details.) __________________________________________________________________ 25 GATING MODES Triggering can be suppressed by a TTL-level signal on the rear-panel GA TE connector. The instrument can be set to stop triggering when this input high or lo w, using the front- panel gate menu or the appropriate programming commands. When gated, th e output will complete the full pulse width if the output is high, and then stop triggering. Pulses are not truncated. OPERATION AT LOW AMPLITUDES This instrument will generate the best waveforms when operated near max imum amplitude. If amplitudes less than ~ 4% of the full-scale value are des ired, better results will be obtained if the pulse generator is operated at a higher amplitu de, and an attenuator is connected to the output. Avtech recommends the BW-SxxW2+ series of 18 GHz coaxial attenuators fr om Mini- Circuits, http://www.minicircuits.com/. (The “xx” in the part number is replaced with the numeric attenuation value in dB). __________________________________________________________________ 26 OPTIONAL FEATURES RACK MOUNTING, "-R5" OPTION A rack mounting kit is available. The "-R5" rack mount kit may be insta lled after first removing the one Phillips screw on the side panel adjacent to the front handle. DC OFFSET, "-OT" OPTION This option adds an internally-generated 0 to ±5V DC offset to the main output. The offset level is set by the front-panel controls, or by computer command s. The rear-panel OS switch must be set to “ON” to activate the internally-generated offs et feature. DC OFFSET, "-EO" OPTION This option allows adds a DC offset to the main output, which is contro lled by an externally generated 0 to +10V analog control voltage applied to a rear -panel connector. MONITOR OUTPUT, "-M" OPTION The monitor output provides an attenuated replica (÷ 11) of the voltage on the main output. The monitor output is designed to operate into a 50 Ohm load. T he monitor output does not include the effect of the internal 15 dB attenuator that is us ed to provide main output amplitudes of 3.4V or less. ELECTRONIC AMPLITUDE CONTROL, "-EA" OPTION The output amplitude can be set to track the voltage on this input. Zer o Volts in corresponds to zero amplitude output, and +10V in corresponds to maximu m amplitude out. This mode is activated by selecting "Ext Control" on the front-pan el amplitude menu, or with the "source:voltage external" command. __________________________________________________________________ 27 PROTECTING YOUR INSTRUMENT TURN OFF INSTRUMENT WHEN NOT IN USE The lifetime of the switching elements in the pulse generator module is proportional to the running time of the instrument. For this reason the prime power to the instrument should be turned off when the instrument is not in use. In the case of failure, the switching elements are easily replaced following the procedure describe d in a following section. DO NOT EXCEED 10 MHz The output stage may be damaged if triggered by an external signal at a pulse repetition frequency greater than 10 MHz. USE A 50 OHM LOAD The output stage may be damaged if the output is not terminated into a 50Ω load. __________________________________________________________________ 28 OPERATIONAL CHECK This section describes a sequence to confirm the basic operation of the instrument. It should be performed after receiving the instrument. It is a useful lear ning exercise as well. Before proceeding with this procedure, finish reading this instruction manual thoroughly. Then read the “Local Control” section of the “Programming M anual for -B Instruments” thoroughly. The “Local Control” section describes the fron t panel controls used in this operational check - in particular, the MOVE, CHANGE, and A DJUST controls. AVTECH SAMPLING PULSER OSCILLOSCOPE BW > 10 GHz MAIN OUTPUT 50 OHM INPUT CONNECTOR 40 dB AC ATTENUATOR POWER TRIG TRIG CONNECTOR CONNECTOR ALL CABLES: 50 OHM COAXIAL BASIC TEST ARRANGEMENT 1. Connect the pulse generator to a sampling oscilloscope as shown abo ve. Note that: a) The use of 40 dB attenuator at the sampling scope vertical input ch annel will insure a peak input signal to the sampling scope of less than 1 Volt. F actory tests are conducted using Mini-Circuits model BW-S20W2+ attenuators. b) The TRIG output channel provides TTL level signals (approximately 0 and +3V). To avoid overdriving the TRIG input channel of some scopes, a 20 dB attenuator may be required at the input to the scope trigger channel. c) The bandwidth capability of components and instruments used to disp lay the pulse generator output signal (attenuators, cables, connectors, etc.) s hould exceed 10 GHz. d) Set the oscilloscope to trigger externally with the vertical settin g at 100 mV/div and the horizontal setting at 10 ns/div. __________________________________________________________________ 29 2.

A large number of commands are available; however, normally you will only need a few of these. Here is a basic sample sequence of commands that might be sent t o the instrument after power-up: *rst (resets the instrument) trigger:source internal (selects internal triggering) frequency 1000 Hz (sets the frequency to 1000 Hz) pulse:width 50 ns (sets the pulse width to 50 ns) pulse:delay 20 ns (sets the delay to 20 ns) volt:ampl 5 (sets the amplitude to +5 V) ("-N" units should use "volt:ampl -5) output on (turns on the output) For triggering a single event, this sequence would be more appropriate: *rst (resets the instrument) trigger:source hold (turns off all triggering) pulse:width 50 ns (sets the pulse width to 50 ns) output on (turns on the output) volt:ampl 5 (sets the amplitude to +5 V) ("-N" units should use "volt:ampl -5) trigger:source immediate (generates a single non-repetitive trigger event) trigger:source hold (turns off all triggering) output off (turns off the output) To set the instrument to trigger from an external TTL signal applied to the rear-panel TRIg connector, use: *rst (resets the instrument) trigger:source external (selects internal triggering) pulse:width 50 ns (sets the pulse width to 50 ns) pulse:delay 1 us (sets the delay to 1 us) volt:ampl 5 (sets the amplitude to +5 V) ("-N" units should use "volt:ampl -5) output on (turns on the output) These commands will satisfy 90% of your programming needs. __________________________________________________________________ 32 ALL PROGRAMMING COMMANDS For more advanced programmers, a complete list of the available command s is given below.

With the four screws removed, the top cover may be slid back (and off). Always disconnect the power cord and allow the instrument to sit unpow ered for 10 minutes before opening the instrument. This will allow any internal sto red charge to discharge. There are no user-adjustable internal circuits. For repairs other than fuse replacement, please contact Avtech (info@avtechpulse.com) to arrange for the instrum ent to be returned to the factory for repair. Service is to be performed solely b y qualified service personnel. Caution: High voltages are present inside the instrument during normal operation. Do not operate the instrument with the cover removed. RACK MOUNTING A rack mounting kit is available. The -R5 rack mount kit may be install ed after first removing the one Phillips screw on the side panel adjacent to the front handle. ELECTROMAGNETIC INTERFERENCE To prevent electromagnetic interference with other equipment, all used outputs should be connected to shielded loads using shielded coaxial cables. Unused ou tputs should be terminated with shielded coaxial terminators or with shielded coaxia l dust caps, to prevent unintentional electromagnetic radiation. All cords and cables s hould be less than 3m in length. __________________________________________________________________ 35 MAINTENANCE REGULAR MAINTENANCE This instrument does not require any regular maintenance. On occasion, one or more of the four rear-panel fuses may require repla cement. All fuses can be accessed from the rear panel. See the “FUSES” section for details. CLEANING If desired, the interior of the instrument may be cleaned using compres sed air to dislodge any accumulated dust. (See the “TOP COVER REMOVAL” section for instructions on accessing the interior.) No other cleaning is recommend ed. __________________________________________________________________ WIRING DIAGRAMS WIRING OF AC POWER 1 2 3 4 5 6 Do no t attem pt a ny r ep air s on this i nstr ume nt Mains circuits - hazardous live. beyon d the fuse r epla cem ent p ro cedur es de scr ib ed i n the m anual .
